Doug I use DM-780 and discovered the same thing you are experiencing once in
a while. I finally figured out what I was doing wrong. I narrowed down my
K3 filter to 250 hz and saw on the display that I was centered on 1500 hz in
Data A mode but when I switched to AFSK for RTTY it was centered on
Doug,
DM-780 appears to start with its tuning guides at 1415/1585, which does not
match any of the K3's RTTY pitch settings exactly, but is quite close to the
K3's 1445 Hz setting. With the K3 in AFSK A sub-mode, hold the K3's PITCH
button (just above the VFO B knob) to see the pitch displayed in
In my previous message I forgot to mention one other difference between AFSK
A and DATA A sub-modes. In AFSK A, the K3's dial displays the actual mark
frequency, whereas in DATA A the dial displays the suppressed carrier
frequency.
Thus, to tune in the W1AW RTTY bulletins on 14095 kHz, in AFSK A
I am trying to determine if I am trying to track down a problem that
doesn't have an answer. I have a on and off problem, with AFSK A and
RTTY. I key and send tones, see bars on ALC but get no RF and do not
hear anything on Monitor playback.
Everything works OK in Data A both RTTY and
Doug.
You have your tones set on the K3 Pitch to something different than
your digital mode software is set to. If you set them to the same
(usually 2125 with 170Hz shift) you will be all set.
